Dear Sujan/Bemmu/Others<p>I constantly fear the Japanese and other Asians may have invented cool things that I am unaware of.<p>I have discovered Japanese sweets, Japanese hot water bottles (the metal tortoises) and Korean washlets.<p>What else is there to discover?!<p>Little known fact as we head into Winter.<p>Japanese hot water bottles remain hot for much longer than the Western rubber versions, your hot water bottle remains warm until noon the next day.
